lsdependentvdisks
Use the lsdependentvdisks command to view which volumes go offline if you remove a specific piece of hardware from the system.
Syntax
>>- lsdependentvdisks --+----------+--+---------------------+---> '- -nohdr -' '- -delim --delimiter-' >--+- -node --+-node_name-+-------------------------------------------------------+->< | '-node_id---' | +- -controller --+-controller_name_list-+--------------------------------------+ | '-controller_id_list---' | +- -mdisk --+-mdisk_name_list-+------------------------------------------------+ | '-mdisk_id_list---' | +- -drive --drive_id_list------------------------------------------------------+ '- -enclosure --enclosure_id--+----------------+--+--------------------------+-' '- -sem --sem_id-' '- -canister --canister_id-'
Parameters
- -nohdr
- (Optional) By default, headings are displayed for each column of data in a concise style view,
and for each item of data in a detailed style view. The -nohdr parameter
suppresses the display of these headings.Note: If there is no data to be displayed, headings are not displayed.
- -delim delimiter
- (Optional) By default in a concise view, all columns of data are space-separated. The width of each column is set to the maximum possible width of each item of data. In a detailed view, each item of data has its own row, and if the headers are displayed, the data is separated from the header by a space. The -delim parameter overrides this behavior. Valid input for the -delim parameter is a one-byte character. If you enter -delim : on the command line, the colon character (:) separates all items of data in a concise view; for example, the spacing of columns does not occur. In a detailed view, the data is separated from its header by the specified delimiter.
- -node node_name | node_id
- (Optional) Specifies the node for which volume dependency is required.
- -controller controller_name_list | controller_id_list
- (Optional) Specifies the controllers for which volume dependency is required.
- -mdisk mkdisk_name_list | mkdisk_id_list
- (Optional) Specifies the MDisks for which volume dependency is required.
- -drive
- (Optional) Specifies the drives for which volume dependency is required. There is a maximum of 128 entries.
- -enclosure enclosure_id
- (Optional) Specifies the enclosure for which volume dependency is required. You can remove a control enclosure without affecting your other data.
- -sem sem_id
- (Optional) Specifies the volumes that are dependent on secondary expander module
availability. The possible values are 1 and 2. Note: If you do not specify -sem this command shows the volumes that are dependent on the enclosure.
- -canister canister_id
- (Optional) Specifies an enclosure canister. The possible values are 1 and 2.
Description
Use this command to view which volumes go offline if you remove a specific piece of hardware from the system. Use this command to determine which volumes are affected before undergoing maintenance.An invocation example
lsdependentvdisks -delim : -drive 0:1
The resulting output:
vdisk_id:vdisk_name
4:vdisk4
5:vdisk5
Note: This means that if drives 0 and 1 are
removed, then volume vdisk4 and volume vdisk5 go
offline.
